Hot reload

Or reloading the state of the application in the process of running, without stopping the processing of requests and breaking connections. The configuration file will be re-read with the new state.

The reload event is attached to the user signal SIGUSR1.

The application can be reloaded using the console command:

pkill -USR1 cpdy

There are two modes for handling active connections after a reboot, they are soft and hard. In the configuration file, the mode is set by the reload property.

    "main": {
        "reload": "hard",

In soft mode, active connections will be terminated when the connection expires or when the connection is closed by the client.

In hard mode, active connections will be forced to close as quickly as possible.
